Original application-fled October 21, 1925, Serial No. 64,048.

December 22, 1925. Serial No. 76,989.

This invention relates to an improvement in valves and is a division ofmy former application Serial No. 21, 1925.

I The object of the invention is'to provide an improved valve which may be automatically actuated by either suction or pressure for controlling the supply of fluid therethrough.

A further object of the invention is to provide a valve ofthis character which may receive and mix two or more different fluids and for controlling the passage of these mixed fluids'therethrough.

In carrying out this invention, a valve casing is provided with a transverse partition therein,'which has-a suitable valve seat in the center thereof for receiving the disk of a spring actuated valve, the latter carrying a needle-valve stem which extends into a nipple projecting into the valve casing from the cap thereof, and which nipple is also provided with a valve seat forreceiving the needle valve stem. The partition within the 25 valve casing separates the same into separate compartments, one of which is adapted to receive the fluids and mix the same before allowing them to pass, through the first mentioned valve into the other compart- 8o ment. Consequentl the supply pipe for one of the fluids is connected with the nipple while-the other with that samecompartment througlrthe side thereof. The fluids thus pass into .one

VII of the compartments and are mixed after which.they pass through'the valve in the partition .intothe other compartment or out through a suitable pipe. A by-pass is provided in the partition so as to allow a small quantity of one fluid to pass therethrough even when that valve is closed. For the purpose of illustrating my invention, I have shown in the accompanying drawings a form thereof which is at present preferred by me,

' #5 since it will give in practice satisfactory and reliable results, although it is to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized and that my 60 invention is not limited to the precise arrangement and organization of these instrumentalities as herein shown and described.

The accompanying drawing is a vertical 64,046, filed October the cap supply pipe communicates section through a valve made in accordance with this invention.

A valve casing 1 is provided with a cap 2 at the lower end thereof and a cover '3 at the opposite or upperend. This casing 1 is also provided with a transverse partition 4 therein, which has a valve seat 5 for receiving a valve disk 6. The flat valve disk 6 is formed-on the valve stem 7 which is slidable through anopening in the web 8 extending across through the lower end of 2 and a spring 9 surrounds the valve stem 7 and is interposed between the web 8 and the valve disk 6 for normally forcing and holding the disk on its seat 5.

An elbow 10 is formed in the cover plate 3 and said elbow has an orifice 11 in the lower end thereof, forming a valve seat for receiving the upper end of the needle valve stem 12, which extends upwardly from and iscarried by the valvedisk 6. A manually controlled needle valve 13 is provided in the upper end of the elbow for controlling the passage of fluid into said elbow from the pipe 14, which is connected with the upper end thereof.

The lower end of the cap 2 terminates in an extended nipple 15, the exterior of which is threaded to be screwed into any suitable device to which'the valve is adapted to be applied as the intake manifold of an internal combustion engine. A by-pass 16 in the form of a small orifice is provided in the partition 4 in order to allow a small quantity of fluid to pass through the valve even when tzhe valve 6 is on is seat. A pipe 1 is tap ed into t e up er compartment 18 of thd valve into whiiih the elbow 10, also, extends. This compartment 18 forms a mixing chamber for the fluids When ever the valve is used as a mixing valve and the compartment 19 below the serves as an outlet for the fluids.

The valve partition 4 seat the needle valve12 is likewise unseatedso as to allow the fluid to pass from the pipe Divided and this application mm disk '6 may be unseated byeither suction or pressure but preferably.

14 into the mixing chamber 18. The valve 13 controls the quantity of fluid which passes due to the fact that air is non-combustibleit is necessary to place the mixing valve on the intake manifold and connecting thereto. This is designed to permit the restricted or unlimited quantities of air to pass into the motor by unseating the valve 6 which is automatically 'justing screw or reliable results,

drawn from its seat as the air is drawn in through opening 17 at atmospheric pressure from any suitable source. Valve 11 automatically unseats with the unseating of valve 6, which permlts the gasoline to flow through pipe 14, the quantity of which is manually adjusted through the advalve 13. This operation permits gasoline and air to be mixed in proper proportions and to enter the motor which causes the motor to revolve more rapidly rather than stall, due to the additional amount of fuel which is permitted to be drawn into the motor. The constantly open bypass 16 is provided to permit a small amount of air to pass through the pipe 17 without unseating the valve 6. Should the slight leak mentioned above open the valve 6, the high vacuum created when the motor is idling would permit too much gasoline to pass through the pipe 14 and would result in making a too rich mixture causing the motor to stall or c oke.

It will now be apparent that I have devised a novel and useful valve which embodies the features of advantages enumerated as desirable in the statement of the invention and the above description, and while I have, in the present instance, shown and described a preferred embodiment thereof which will give in practice satisfactory and it is to be understood that the same is susceptible of modification in various particulars without departing from the spirit or scope of-the invention or sacrificing any of its advantages.

I claim:

1. In a device of the character stated, a

needle valve seat in casing, a closure for its upper end, an elbow in said closure, a manna ly operated valye for said elbow, a valve 'seatin' said elbow, a the lower end of said elbow, a valve seat within said casing, an automatic disc valve for said latter seat, a needle valve on the upper portion of said disc valve, and seating m said elbow, a secondary inlet to said mixingchamber formed above said disc valve, a spring for constantly pressing said disc valve against its seat, and a constantly open by-pass leading from said mixing chamber to-the outlet from said casing.

2. In a device of the character stated, a casing, a closure for its up er end, an inlet conduit passing throu h .sai closure, a valve seat in said inlet con uit, a manually operated valve located above said seat, a valve seat in the lower end of said conduit a chamber in said conduit betweensaid valve seats, an automatic valve located in about the cen-- tral part of said casing, a seat therefor, a spring exertin' tension on-said valve and normally pressing the same against its seat a needle valve carried by said valve an adapted to engage the seat atthe bottom of said inlet conduit, a secondary inlet pipe leading into the mixing chamber formed above said centrall disposed disc valve, and a constantly open y-pass leading from said mixing chamber to the outlet from saidcasing.

3; In-a device of the character stated, a casing, a closure for its upper end, an inlet conduit passin throu h said closure,-a valve seat in said in et'con uit, a manually operated valve located above said seat, a needle valve seat in the lower end of said conduit, an automatic valve located in about the central part of said casin a transverse partition located at about the central portion of said casing and having a valve seat for said automatic valv'e therein, a spring bearing on the underside of saidautomatic valve and normally pressing the same against its seat, a needle valve carried by said automatic valve and adapted to seat in the bottom of said inlet conduit, a second inlet pipe leading into said mixing chamber at a point above said centrally disposed automatic valve, and a constantly open by-pass adjacent said disc valve, and leading from said mixing-chamber to the outlet from said cas- In testimony whereof I affix my signature.
